Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores.
There was a major increase in syphilis cases during the 2000s, especially among women ages 20 to 24 and men ages 35 to 39. If syphilis goes untreated, the affected person is at risk of developing neurosyphilis. This is an infection of the nervous system, specifically of the brain and the spinal cord. Neurosyphilis is a life-threatening disease. Advertisement.
